what ionic compounds could you form from the following?

Question

Sodium
Calcium
Neon
Phosphorus
Chlorine

i have NaCl, CaCl2, Na3P, and Ca3P2

is that all and can neon be used?

Answer 1

I think you have all of them. P and Cl will form PCl3 and PCl5 but those compounds are polar covalent (Electronegativity difference of about 1 so they are about 25% ionic and 75% covalent [approximately]).
